Checking for unnecessary polygon boundaries

Unnecessary boundaries sometimes exist where adjacent polygons have the same editable field attribute values. In some instances, the two features should be merged into a single feature.

The Unnecessary Polygon Boundaries check finds polygon features within a single feature class that are adjacent to one another and have identical attribute values on editable fields. The chosen feature class can optionally be a part of a database topology. Different algorithms are used to find unnecessary polygon boundaries for feature classes that have topology and those that do not. Optionally, fields that are considered feature-level metadata can be excluded from consideration. This check can be run on an entire feature class, a subtype, or a set of features that have been selected using a SQL query.

Once you have defined the criteria for the check, you can configure the notes and a severity rating. The notes allow you to provide a more specific description for the feature that has been written to the Reviewer table and are copied to the Notes field in the Reviewer table. The severity rating allows you to indicate how important the results from a check are in terms of your quality assurance/quality control processes. The lower the number, the greater the priority the check's results have.

If necessary, type a unique name for the check in the Check Title text box.

Note:

The check title can be used to describe the conditions you are looking for with the check. This is useful when you have multiple instances of the same check to validate the same feature classes or tables but with different validation parameters.

Click the Feature Class/Subtype drop-down arrow to choose the feature class and subtype on which to run the check.

To run the check on the entire feature class and save this setting, check the Always Run on Full Database check box.

To run the check on specific features in a feature class, click SQL to construct an SQL query.

If you want to ignore feature-level metadata, do the following:

Check the Attributes to Ignore (Feature Level Metadata) check box.

Click Select Attributes.

The Attributes To Ignore dialog box appears.

Check the check boxes next to the names of the attributes you want to ignore when finding spatial relationships.

Note:

To check or uncheck all the check boxes next to the attribute names, click Select All or Clear All, respectively.
